2 Claims. (Cl. 7-8.1)

My present invention relates to an adz attachment for hammers, and the like.

- One of the principal'objects-of this invention is to provide an adz attachment of this class which may be secured to the head of a hammer in variou positions so that it may be used either as an adz or a hand ax or hatchet, with only a slight and easy and quick adjustment.

Another object of this invention is to provide an attachment of this class for hammers, and the like, in which the blade member may be securely connected to the head of the hammer so that it may be easily removed therefrom.

An important object also of this invention is to provide an adz attachment of this class which may be readily applied or attached to hammers of various types;

A further object of this invention is to provide novel and simple means of clamping the adz attachment to the neck of the head of a hammer.

With these and other objects in view, as will appear hereinafter, I have devised an adz attachment for hammers and the like, which attachment has various novel features of construction, combination, and arrangement of parts and portions, as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawing and to the characters of reference thereon, which form a part of this application, in which:

Fig. 1 is a fragmentary side view of a carpenter hammer with my adz attachment, in a preferred form, secured to the end of the head of the hammer;

Fig. 2 is a sectional elevation of the blade portion of my attachment taken through 2 2 of Fig. 1;

Figs. 3, 4, and are sectional views thereof taken, respectively, through 33, 4-4, and 5-5 of Fig. 1; and,

Fig. 6 is another fragmentary side view of a carpenters hammer with my adz attachment secured to the side of the head of the hammer sothat the hammer and attachment may be used as a hand ax or hatchet.

My adz attachment, as shown in the drawing, consists essentially of ablade member I and a simple means A for securing it to the head 2 of the hammer 2.

The blade member is a relatively thin convexly or outwardly curved plate of tool steel, relatively wide at its lower end, providing the sharp or cutting edge I of the tool, and relatively narrow at its upper end. Intermediate these ends is an opening or recess for receiving the striking portion 2 of the head of the hammer, as hown in Figs. 1 and 4. At the bottom of the opening or recess is a shelf or ledge N which is offset toward the inner side of the blade member, and the ledge forms the "lower edge of the opening or recess.

, The face 2 of the striking portion 2 of the hammerhead 2? rests on this ledge and the front side of the head engages the upper end portion 'l of the blade member. This upper end may be provided with a longitudinal depression or groove I for receiving any portion of the handle extending beyond the head, or to accommodate any head which may be rounded at the front side. The portion of the blade member forming the sides of the opening or recess I is shaped so as to receive and rigidly anchor the sides of the striking portion 2* of the hammer, as shown in Figs. 2.

and 4..

The securing means A, a shown, consists of a yoke or U-shaped clamp member 3, a link or loop member 4, and a clamp screw 5. The U-shaped clamp member 3 is adapted to straddle or encompass the neck 2 of the hammer, as shown in Figs.

land 3. The end of the leg 3 of the clamp member 3 is pivotally connected, by means of the link 4, to One edge of the blade member, as shown best in Fig. 3. The link extends through a hole I of the blade member and the portion of the blade member outwardly from the hole i offset inwardly, as shown in Figs. 1 and 3, in order to recess the outer end of the link inwardly from the outer face of the blade member. The other leg 3 of the clamp member has a round or bolt portion 3 which is provided at the outer end thereof with a tapered rivet head 3 The opposite edge portion of the blade-member has a transverse slot l which is provided at its inner end with a tapered or conical seat i for receiving the correspondingly tapered outer end of the leg 3*. Thus, the'clamp member may be readily placed around the neck portion of the hammer and the outer end of the leg 3 may be readily inserted into the slot l The blade member is clamped against the outer face of the head of the handle by means of the adjustingscrew 5 which extends through the connecting portion of the U-shaped clamp member. This screw may be readily adjusted with a wireor nail, usually carried by a carpenter who may use the tool.

It will be here noted that the legs of the clamp member and also the link 4 are so shaped that they may spring slightly when the blade member is clamped into position.

The blade member I is so designed that it may fit against the outer side of the head of the hambalanced when the blade member is secured to V 1 either of the opposite lateral sides of the head of the hammer.

The end portion l of the blade member is shown as provided with a suitable non-slip memher 6 which is made of a softerand :more resilient material. This non-slip member is intended to hold the upper end of the blade'mem ber more securely against the smooth lateral sides of the head'of the hammer.

Though I have shownand'described a particu lar construction, combination; and arrangement of parts and portions of my adz attachment for hammers, I do not wish to be limited to the same, but desire to include in the scope of my invention the construction, combination, and arrangement, substantiallyas set forth in the appended claims. a 1 l I claim: a 1. In an adz attachment for hammers, a blade member having a cutting edge at one end'anda ledgeintermediate the ends adapted to receive the face of the head of the hammer, said ledge being pressed from the blade to one side of the plane of the blade, and means for clamping the blade member against the various portions of the side of the neck of the head of the hammer with the cutting edge positioned in the direction f of but beyond the head.

2. In an adz attachment for hammers a blade having :a cutting edge atone end and a ledge intermediatetheends adapted to receive the face 7 of the head of the hammer, and a clamp means 'forembracing the neck of the head of the hammerv for clamping the blade member to the hammer with the cutting edge positioned in the direction of but beyond the head, said clamp means 5 comprising a U-shaped member having two legs, one p vo al o nectedz o oneedae of the blade member, and the other being :Vadapted to be removably connected to":the;blade member adjacent. the oppositeedge, and a: screw in the con- 7 necting' portion of the U-shaped member adapted to engage the jneck-for drawing'the blade against the opposite-side of the head.
